Given the following chemical equation... 4P+5O2➡️ 2 P2O5
How many moles of P2O5 are formed from 3.4 moles of of O2? (show the math below) ⬇️

The moles are the base unit of a given substance. The number of moles in P₂O₅ that are formed from 3.4 moles of oxygen is 1.36.

Given that:

Number of moles of P₂O₅ = ?

Number of moles of O₂ = 3.4 moles

The balanced chemical reaction can be given as:

4P  +  5O₂  ⇒   2P₂O

Now, by the stoichiometry of the reaction, it can be assumed as:

5 moles of Oxygen = 2 moles of P₂O₅

3.4 moles of oxygen = x

Thus, the value of x:

x = 1.36 moles of P₂O₅.

Therefore, in 3.4 moles of oxygen, 1.36 moles of P₂O₅ will be produced.

The answer to your question is  1.36 moles of P₂O₅

Explanation:

Data

moles of P₂O₅ = ?

moles of O₂ = 3.4 moles

Balanced chemical reaction

                4P  +  5O₂  ⇒   2P₂O₅

To solve this problem use proportions and cross multiplication. Consider the coefficients of the molecules of the balanced equation.

                 5 moles of O₂ 2 moles of P₂O₅

                 3.4 moles of O₂  x

                           x = (3.4 x 2) / 5

-Simplification

                          x = 6.8 / 5

-Result

                          x = 1.36 moles of P₂O₅
